BOTTLECAP Filed June 29, 1945 Patented Aug. 17, 1948 BOTTLE CAP Frank Vogel, Philadelphia, Ba, assignorto Philip A. Udall Distributing 00., Inc, a corporation of New York Application June 29, 1945, Serial No; 602,266

9 Claims. 1

My invention relates to a new and useful bottle cap and particularly to improvements on the invention disclosed in my co-pending application, Serial No. 573,873.

One of the objects of the present invention is to provide an exceedingly simple and eifective cap for temporarily closing a bottle after the original closure has been removed.

Another object of the invention is to so combine the elements of the unitary structure that the cap will be drawn down tightly upon the mouth of a bottle to positively seal the same and prevent escape of the contents whether in liquid or gaseous form.

A further object of the invention is to provide a bottle cap comprising a body having a depending flange with a portion formed to constitute an inclined underslung gripping element for disposition under the lip or bead of a bottle, and a lever of unique formation to engage beneath the bottle lip or bead for pulling the cap down tightly onthe bottle mouth.

Still another object of the invention is to provide a bottle cap that can be fashioned from stampings and including a body or closure element carrying a gasket to seal and compensate for certain uneven formations on the mouth of a.

bottle, said body having means to hold the gasket in place, and an angular locking lever pivoted to ears on the body for drawing the gasket tightly this invention appertains ma understand how.

to make and use the same I will describe its construction in detail referring by numerals to the accompanying drawing forming a part hereof, in which: 7

Fig. 1 is a perspective view illustrating the cap assembled on the mouth of a bottle, the neck portion of which is shown.

Fig. 2 is a side elevation thereof looking towards what will be considered the back of the cap. 7 Y

Fig. 3 -als is a side elevation at right angles to" Fig, 2showing the cap in the initial positionof application to a bottle.

Fig. 4 is a similar view after th sealing operationis complete.

vl 'ig. 5 is a sectional elevation of the bottleneck and capthereon.

Fig. 6 isa similarview illustrating a modified form of lever.

In carrying out theinvention as-herein em bodied, [0 represents the body portion of the cap produced from any suitabl material and fashioned in a shape and size to fit the mouth end of a bottle II which mouth end has a lip or bead l2 surrounding it to provide a shoulder.

A depending fiange zl3 extends partly around.

the body 10 and the front portion is inclined to produce'an underslung gripping element M to be hooked under the lip or bead [2 on a bottle prior to the cap being forced down into sealing posi-- tion. Th balance of the flange is proportioned.

to readily pass over the lip or bead it of the bottle. a

Rearwardly projecting spaced ears l5 extend? from the back portions of the flange l 3 where saidi flange terminates, and each of said ears has a. hole l6 therein. Between these cars I5 is atongue I! dependin from the cap body,- and in. conjunction with the flange l3 and the gripping element I4, functions to frictionally and grasp-- ingly hold a gasket l8 of compressible material within the cap against the inside face of the body" It).

lugs 20 formed integral with the lever, or some equivalent means, such as a pin passing through said lever. The pivoting means register with and are rotatably mounted in the holes I6 in-the ears l5. Saidlocking lever includes a handle portion 2| for applying the necessary force to operate thelever, and a nose 22 to engage underneath of the bottle lip or bead l2 as a fulcrum for drawing down the. rear portion of the cap. The nose 22 is slightly greater than a right angle but, in any case, proportioned and positionedto remain in engagement with the lip or bead of thebottle An angular locking lever I9, Figs. 1 to 5 inclusive, is pivoted between the ears l5 by pivot when the cap is pulled down tightly for maintaining the seal. The outer end of the lever handle, preferably, is fashioned to form a bottle cap remover 23.

In Fig. 6, I have illustrated a modified construction of locking lever I9a comprising a, handle portion 2|a and a nose 22a with pivoting means a. In this form of locking lever, the nose 22a includes a return bend 22b constituting a resilient beak which will engage the bottle lip or bead and compensate for irregularities or varying thicknesses in the lips of bottle of different makes which might not be compensated for by the compressible gasket.

To apply the cap to a bottle and seal the latter, the handle portion of the locking lever is raised and the cap slightly tilted, as shown in Fig, 3*, so-

the underslung gripping element I4 can be en gaged beneath the bottle lip or bead f2. When the rear portion of the cap is' lowered, the nose of the locking lever will assume a position against the bottle lip on the lower half thereof.- The oted at its sides in said ears and including a handle portion and a nose to engage the underside of the bottle lip to force the cap rearwardly and downwardly due to the sliding action of the gripping element.

4. The bottle cap of claim 3 in combination with a resilient beak formed by a return bend on the nose of the locking lever.

5. A bottle cap including a, body proportioned to close the top of a bottle having a lip, a flange extending partly around and integral with the body and having an underslung tor-ward portion for engaging beneath a portion of said lip, a gasket on the inside of said body, a tongue integral with the body and depending from said body, said tongue and flange holding the gasket in position, and a lever pivotally connected to l the rear of the body and adapted to operate in handle portion of the lever is then swungdownwardly and inwardly towards and against the side of the bottle. This causes the pivot point of the lever to rotate about the terminal end of the nose as an axis, where the latter rides on the bottle lip; so that the underslung gripping element is pulled under the bottle lip and the rear of the cap drawn downward until the gasket is firmly compressed on the bottle mouth which tightly seals the bottle.

The pivot point of the locking lever being below the point of contact of the nose with the bottle lip or past a dead center, the capis securely held against accidental displacement and any ordinary pressure within the bottle. By reversing the above mentioned operations, the cap may be easily and quickly removed.

Of course I do not Wish to be limited to'the exact details of construction herein shown and described as these may be varied within the scope of the appended claims without departing from the spirit of my invention.

Having described the invention what I claim as-new and useful is:
